Methods, Apparatuses, and Systems for Detecting Printing Defects and Contaminated Components of a Printer

2. The method of claim 1 further comprising in response to determining that the at least one bright point is non-collinear, determining that the at least one defect in the printed content is caused by contaminated platen roller.

3. The method of claim 1 further comprising determining whether a bright point of the at least one bright point is within a predetermined distance from another bright point the at least one bright point.

4. The method of claim 3 further comprising, in response to determining that the bright point is within the predetermined distance of the other bright point, creating a cluster of bright points that includes the bright point and the other bright point.

5. The method of claim 4 further comprising determining whether the cluster of bright points is collinear based on attempting to connect three bright points in the cluster of bright points on a straight line.

6. The method of claim 5 further comprising in response to determining that the at least one bright point is collinear, determining that the at least one defect is caused by wrinkles on a ribbon.

7. The method of claim 5 further comprising connecting the at least one bright point to create the line.

8. The method of claim 7 further comprising determining a slope of the line and comparing the slope of the line with a predetermined angle.

9. The method of claim 8 further comprising detecting the cause of the at least one defect as wrinkles on a ribbon.

10. The method of claim 1, wherein the printed content includes a barcode symbol.

12. The printer-verifier apparatus of claim 11, wherein the verifier is configured to, in response to determining that the at least one bright point is non-collinear, determine that the at least one defect in the printed content is caused by contaminated platen roller.

13. The printer-verifier apparatus of claim 11, wherein the verifier is further configured to determine whether a bright point of the at least one bright point is within a predetermined distance from another bright point the at least one bright point.

14. The printer-verifier apparatus of claim 13, wherein the verifier is further configured to: in response to determining that the bright point is within the predetermined distance of the other bright point, create a cluster of bright points that includes the bright point and the other bright point.

15. The printer-verifier apparatus of claim 14, wherein the verifier is further configured to determine whether the cluster of bright points is collinear based on attempting to connect three bright points in the cluster of bright points on a straight line.

16. The printer-verifier apparatus of claim 15, wherein the verifier is further configured to: in response to determining that the at least one bright point is collinear, determine that the at least one defect is caused by wrinkles on a ribbon.

17. The printer-verifier apparatus of claim 15, wherein the verifier is further configured to connect the at least one bright point to create the line.

18. The printer-verifier apparatus of claim 17, wherein the verifier is further configured to determine a slope of the line and compare the slope of the line with a predetermined angle, wherein the verifier is configured to detect the cause of the at least one defect as wrinkles on a ribbon based on the comparison of the slope of the line with the predetermined angle.
